I just bought a recirculated O2 housing set up for an external gate and noticed that where the flange meets the piping it is extremely uneven and rough. Specifically where the wastegate dumps back into the housing there is a rough lip that seems like would effect smooth exhaust gas flow.

Anyone else have any issues like this? I am use to OEM housings.
 
I smoothed mine out, but I dont think there will be much difference if you just leave it alone
